Cinder
Summary

Humans and androids crowd the raucous streets of New Beijing. A deadly plague ravages the population. From space, a ruthless Lunar people watch, waiting to make their move. No one knows that Earth’s fate hinges on one girl. . . .
Cinder, a gifted mechanic, is a cyborg. She’s a second-class citizen with a mysterious past, reviled by her stepmother and blamed for her stepsister’s illness. But when her life becomes intertwined with the handsome Prince Kai’s, she suddenly finds herself at the center of an intergalactic struggle, and a forbidden attraction. Caught between duty and freedom, loyalty and betrayal, she must uncover secrets about her past in order to protect her world’s future.
So yeah, we got a Cinderella cyborg, who is quite a flawed heroine, but I think it makes for a more relatable and human teen character. She really just wants out of her messed up life but ends up being way more important to the situation of the moon people wanting to take over the Earth. This book isn't going to be the next classic to be read in future AP English courses, but it's really fun and engaging and filled with interesting characters.
